[EN] This study was overall objectives , analyze the performance of normal adults Portuguese executives of both sexes , taking into account the different components that make up the executive functions and consider whether, in the elderly , executives yields relate to social activities and with basic and instrumental activities of daily living .Specifically , we have tried to determine whether there are variations in the performance of executive duties and overall capacity of inhibition, cognitive flexibility , planning, and verbal fluency according to sex , age, and educational level. We have studied the association between executive performance and conducting social activities. The relationship between executive performance and execution of basic and instrumental activities of daily living has also been analyzed in this study.The sample consists of 272 Portuguese participants ( 102 men and 170 women) aged between 18 and 88 years with different educational levels without neurological disease . Participants were divided into three groups according to age as follows : Seniors ( 65 years ) , adults ( 40-64 years) and Youth ( 18-39 years). Subsequently, in each age group , participants were grouped by the number of years of schooling who have served as follows : low educational level ( 9 or fewer years of schooling) , middle education level (10-12 years of schooling ) and highly educated (13 or more years of schooling) . In the Senior Adult group has been formed another group with no schooling ? ? Wherein participants are included who have never entered the education system. None of the participants presented cognitive impairment, estimated from the score of the Mini Mental State Examination ( Folstein , Folstein , and McHugh, 1975) , or depression , assessed from the results of the Beck Depression Inventory (Beck, Ward, Mendelson , Mocke and Erbough , 1961 ) . Participants performed the following tests : Wisconsin Card Sorting Test ( Heaton, Chelune , Talley , Kay, and Curtiss, 1981) , Stroop Neuropsychological Screnning Test ( Trenerry , Crosson , Deboe , and Leber, 1989) , Set Test ( Isaacs and Khatar , 1972) , Creep Test of Shares ( Piatt , Fields , Paolo , and Troster , 1999) , Comprehensive Trail Making Test (Reynolds , 2002) , Tower of London ( Culbertson and Zillmer , 2005) , Frontal Assessment Battery ( Dubois, Slachevsky , Livtan and Pillon , 2000) , Barthel Index (Mahoney and Barthel, 1965) and Lawton and Brody Index ( Lawton and Brody, 1969). Participants Seniors Group have complied List of Daily Activities ( Ghisletta , Bicker , and Lovén , 2006).With the exception of verbal fluency , the components of executive functions undergo a change in old age as evidenced by a decline in the overall business performance , capacity inhibition , cognitive flexibility , planning and action fluency . Yields on tests of phonological and semantic verbal fluency were not affected by aging. We observed a main effect of educational level. Regardless of age , the best performances have made the participants with higher educational levels ( medium and high) . This result suggests that the executive decline is slower if the education level is high. The gender variable was only predictive value yields CTMT . The results concerning the relationship between social activity and yields executives indicate that participation in this activity is associated with better executive functioning. The basic and instrumental activities of daily living are negatively related to the execution time required to plan and plan a task.
